“…Most researchers insisted that it is much easier to incorporate the philosophy of IPD, namely some IPD principles, rather than the practice of IPD, into construction projects to improve their performance. For instance, contract provisions and project procedures can be modified to encourage the early involvement and collaboration of the project team [20,21]. Some customized contract forms and terms other than an IPD multiparty contract can effectively handle the defects in scheduling performance [11,15].…”

Although integrated project delivery (IPD) is still in its infancy in the construction industry worldwide, some principles can be effective without formal contractual languages and enforcements when IPD is employed as a philosophy as opposed to a delivery method. This paper aims to investigate the effect of IPD principles on project performance in China, providing a reference for improvement of project performance by the application of IPD principles in countries or regions where IPD is considered as a philosophy. A total of 205 data samples were collected from different IPD-related participants in China via a questionnaire survey. Eight hypotheses are proposed based on a literature review, and these are verified using a structural equation model (SEM). According to the results of the exploratory factor analysis, IPD principles, including behavioral principles, contractual principles, collaboration-related principles, and catalysts, are classified, and the internal relationship of various IPD principles is explored using SEM to analyze the impact path between IPD principles and project performance. It was discovered that project performance is directly affected by collaboration-related principles and catalysts. The contractual principles have positive impacts on both behavioral principles and collaboration-related principles, while the catalysts show positive impacts on behavioral principles. This work provides insights and managerial implications for local applications of IPD for construction practitioners, which should be considered by promoting regional IPD practices; it contributes to both theoretical and practical perspectives for improving project performance by the effective implementation of IPD in construction projects.

“…The complex nature of processes in water and wastewater treatment facilities require highly specialized expertise in planning, cost estimating, design and construction of such facilities. This type of construction includes rehabilitation, expansion and new construction of these treatment facilities, and requires a highly skilled team of individuals to ensure a successful project undertaken by large construction firms (Abi Shdid and Andary, 2016). Water and wastewater construction projects have historically been delivered using the traditional design-bid-build (DBB) delivery method and have therefore suffered from shortcomings inherent to DBB (Abi Shdid and Andary, 2016).…”

Water and wastewater construction projects have historically been delivered using the traditional design-bid-build (DBB) delivery method and have therefore suffered from shortcomings inherent to DBB (Abi Shdid and Andary, 2016). This is partly due to the public nature of these projects and the existing public contract laws that make implementation of integrated project delivery (IPD) in public projects rather challenging.…”

Purpose The public nature of water and wastewater construction capital projects has rendered design-bid-build (DBB) as the delivery method of choice for such projects over the past years. Shortcomings inherent to DBB have had a negative effect on the key performance indicators (KPIs) of these projects. Numerous studies have been published about the benefits offered by integrated project delivery (IPD) in improving the delivery of DBB projects. Links correlating IPD principles to improvements in KPIs of DBB construction projects have not been established scientifically, thus leaving owners with no guidance on which IPD principle(s) to implement in order to improve a particular project KPI. The paper aims to discuss this issue. Design/methodology/approach Actual data were collected from 43 water and wastewater construction projects – including two control projects with full implementation of selective IPD principles – and used to compute major projects KPIs. Regression analysis and a focus group are then utilized to determine the effect of each implemented IPD principle on various project KPIs. Findings Implementation of open communication was found to have a significant effect on reducing project cost overrun, and the co-location of teams significantly reduced the time to respond to RFIs. Collaborative decision making significantly reduced the cost of field rework. Other IPD principles showed less-significant effects on project KPIs and were concluded to be ineffective at improving the projects’ performance. Practical implications An implementation framework is developed that can guide utility owners on which IPD principle(s) to implement in order to improve specific project KPIs. Originality/value This study demonstrates that not all IPD principles will result in performance improvement of a project. A selective and cost-effective implementation of certain IPD principle will have to be based on the nature of the project and the particular KPIs targeted for improvement.
